MCQ
$A$ straight line joining the object point and image point is always perpendicular to the mirror
- Aif mirror is plane only
- Bif mirror is concave only
- Cif mirror is convex only
- ✓irrespective of the type of mirror.
✓
Answer
Correct option: D.
irrespective of the type of mirror.
d
Any line joining the object point and the image point always passes through the centre of curvature of the mirror. This, is because of the law, that any ray passing through the centre of curvature of the mirror will retrace its path back.

Thus, any ray passing through the centre of curvature will be perpendicular to the mirror irrespective of the type of the mirror used.
